The 'Pretty Little Liars' Creator Told Us the Show's Ending Three Years Ago

UPDATE, June 29 at 2 P.M. EST: I. Marlene King isn’t the only one who hinted that Spencer had an evil twin. Take a look at Troian Bellisario’s Twitter bio:

“Sometimes, I play this chick, Spencer Hastings, on this show Pretty Little Liars. But only sometimes,” she wrote. At first, this sentence seems harmless: Bellisario is simply saying that she’s an actress and isn’t embodying Spencer 24/7. But what if she’s actually saying that her time on PLL was split between two characters: Spencer…and Alex Drake?! The plot thickens.

The wait is over, Pretty Little Liars fans. The series finale aired Tuesday night (June 27), and it revealed everything—including A.D.’s identity. Turns out, Spencer’s evil twin, Alex Drake, was calling the shots all along. And this bombshell would’ve been surprising had it not been a dominant fan theory for years now. The PLL cast and crew did a pretty good job at keeping this hypothesis on a lid, though—well, except for the show-runner, I. Marlene King. She straight-up gave away PLL‘s ending in an interview from over three years ago.

Refinery29 uncovered a 2014 video from The Wrap that features King and some PLL cast members discussing their favorite fan theories. Guess which one IMK picked to discuss…in detail?

“Troian [Bellisario] sent me a theory the other day that I thought was amazing, and it was so well thought-out. It was that Spencer has a twin, and that person is A,” King said. “When I read through all of the information the person delved out, I thought, Oh my gosh, this is a really well thought-out plan, and it’s kind of a good one.”

Yes, my friends, we’ve had the answer to Pretty Little Liars‘ biggest mystery for over three years, but we just didn’t know it. Granted, King didn’t come right out and say, “This is the ending,” but the fact she chose to expand on this particular theory is suspect.

Watch King’s interview, below:

King knew about “Twincer” long before giving this quote. Troian Bellisario revealed to elle.com that King told her about Alex Drake while they were shooting season five, which aired in March 2014.

“I was first told [about the twin] in the beginning of season five. Marlene took me aside and told me, ‘I have an idea, but I don’t know if the network will let me do it….’ Then she sat me down and explained this whole ending to me,” Bellisario said. “She said, ‘You cannot tell anybody. It might not even happen.’ So I sat on it for over a year. Then at the end of season six, she said, ‘We’re going to do it.’ It was like the starting gun at the races.”
